TECHNICAL FIELD

The disclosed embodiments relate generally to portable electronicdevices, and more particularly, to interacting with user input elements(e.g., radio buttons, text input fields, check boxes, pull down lists,and form fields) on portable electronic devices.

BACKGROUND

As portable electronic devices become more compact, and the number offunctions performed by a given device increase, it has become asignificant challenge to design a user interface that allows users toeasily interact with a multifunction device. This challenge isparticular significant for handheld portable devices, which have muchsmaller screens than desktop or laptop computers. This situation isunfortunate because the user interface is the gateway through whichusers receive not only content but also responses to user actions orbehaviors, including user attempts to access a device's features, tools,and functions. Some portable communication devices (e.g., mobiletelephones, sometimes called mobile phones, cell phones, cellulartelephones, and the like) have resorted to adding more pushbuttons,increasing the density of push buttons, overloading the functions ofpushbuttons, or using complex menu systems to allow a user to access,store and manipulate data. These conventional user interfaces oftenresult in complicated key sequences and menu hierarchies that must bememorized by the user.

Many conventional user interfaces, such as those that include physicalpushbuttons, are also inflexible. This is unfortunate because it mayprevent a user interface from being configured and/or adapted by eitheran application running on the portable device or by users. When coupledwith the time consuming requirement to memorize multiple key sequencesand menu hierarchies, and the difficulty in activating a desiredpushbutton, such inflexibility is frustrating to most users.

Furthermore, conventional user interfaces lack a user-friendly way toreceive user input via input elements displayed on the screen, such asradio buttons, text input fields, check boxes, pull down lists, and formfields. Users may experience difficulties in selecting input elements,which may be barely legible or illegible.

Accordingly, there is a need for portable multifunction devices withmore transparent and intuitive user interfaces for interacting with userinput elements that are easy to use, configure, and/or adapt. Suchinterfaces increase the effectiveness, efficiency and user satisfactionwith portable multifunction devices.

SUMMARY

As used in the description ofthe invention and the appended claims, the singular forms “a”, “an” and“the” are intended to include the plural forms as well, unless thecontext clearly indicates otherwise. It will also be understood that theterm “and/or” as used herein refers to and encompasses any and allpossible combinations of one or more of the associated listed items. Itwill be further understood that the terms “comprises” and/or“comprising,” when used in this specification, specify the presence ofstated features, integers, steps, operations, elements, and/orcomponents, but do not preclude the presence or addition of one or moreother features, integers, steps, operations, elements, components,and/or groups thereof.

Embodiments of a portable multifunction device, user interfaces for suchdevices, and associated processes for using such devices are described.In some embodiments, the device is a portable communications device suchas a mobile telephone that also contains other functions, such as PDAand/or music player functions.

The user interface may include a physical click wheel in addition to atouch screen or a virtual click wheel displayed on the touch screen. Aclick wheel is a user-interface device that may provide navigationcommands based on an angular displacement of the wheel or a point ofcontact with the wheel by a user of the device. A click wheel may alsobe used to provide a user command corresponding to selection of one ormore items, for example, when the user of the device presses down on atleast a portion of the wheel or the center of the wheel. Alternatively,breaking contact with a click wheel image on a touch screen surface mayindicate a user command corresponding to selection. For simplicity, inthe discussion that follows, a portable multifunction device thatincludes a touch screen is used as an exemplary embodiment. It should beunderstood, however, that some of the user interfaces and associatedprocesses may be applied to other devices, such as personal computersand laptop computers, that may include one or more other physicaluser-interface devices, such as a physical click wheel, a physicalkeyboard, a mouse and/or a joystick.

The device supports a variety of applications, such as a telephoneapplication, a video conferencing application, an e-mail application, aninstant messaging application, a blogging application, a digital cameraapplication, a digital video camera application, a web browsingapplication, a digital music player application, and/or a digital videoplayer application.

The various applications that may be executed on the device may use atleast one common physical user-interface device, such as the touchscreen. One or more functions of the touch screen as well ascorresponding information displayed on the device may be adjusted and/orvaried from one application to the next and/or within a respectiveapplication. In this way, a common physical architecture (such as thetouch screen) of the device may support the variety of applications withuser interfaces that are intuitive and transparent.

The user interfaces may include one or more soft keyboard embodiments.The soft keyboard embodiments may include standard (QWERTY) and/ornon-standard configurations of symbols on the displayed icons of thekeyboard, such as those described in U.S. patent application Ser. No.11/459,606, “Keyboards For Portable Electronic Devices,” filed Jul. 24,2006, and Ser. No. 11/459,615, “Touch Screen Keyboards For PortableElectronic Devices,” filed Jul. 24, 2006, the contents of which arehereby incorporated by reference herein in their entirety. The keyboardembodiments may include a reduced number of icons (or soft keys)relative to the number of keys in existing physical keyboards, such asthat for a typewriter. This may make it easier for users to select oneor more icons in the keyboard, and thus, one or more correspondingsymbols. The keyboard embodiments may be adaptive. For example,displayed icons may be modified in accordance with user actions, such asselecting one or more icons and/or one or more corresponding symbols.One or more applications on the portable device may utilize commonand/or different keyboard embodiments. Thus, the keyboard embodimentused may be tailored to at least some of the applications. In someembodiments, one or more keyboard embodiments may be tailored to arespective user. For example, one or more keyboard embodiments may betailored to a respective user based on a word usage history(lexicography, slang, individual usage) of the respective user. Some ofthe keyboard embodiments may be adjusted to reduce a probability of auser error when selecting one or more icons, and thus one or moresymbols, when using the soft keyboard embodiments.

Thetouch screen 112 is used to implement virtual or soft buttons and one ormore soft keyboards.

The touch-sensitive touch screen 112 provides an input interface and anoutput interface between the device and a user. The display controller156 receives and/or sends electrical signals from/to the touch screen112. The touch screen 112 displays visual output to the user. The visualoutput may include graphics, text, icons, video, and any combinationthereof (collectively termed “graphics”). In some embodiments, some orall of the visual output may correspond to user-interface objects,further details of which are described below.

A touch screen 112 has a touch-sensitive surface, sensor or set ofsensors that accepts input from the user based on haptic and/or tactilecontact. The touch screen 112 and the display controller 156 (along withany associated modules and/or sets of instructions in memory 102) detectcontact (and any movement or breaking of the contact) on the touchscreen 112 and converts the detected contact into interaction withuser-interface objects (e.g., one or more soft keys, icons, web pages orimages) that are displayed on the touch screen. In an exemplaryembodiment, a point of contact between a touch screen 112 and the usercorresponds to a finger of the user.

The touch screen 112 may use LCD (liquid crystal display) technology, orLPD (light emitting polymer display) technology, although other displaytechnologies may be used in other embodiments. The touch screen 112 andthe display controller 156 may detect contact and any movement orbreaking thereof using any of a plurality of touch sensing technologiesnow known or later developed, including but not limited to capacitive,resistive, infrared, and surface acoustic wave technologies, as well asother proximity sensor arrays or other elements for determining one ormore points of contact with a touch screen 112.

A touch-sensitive display in some embodiments of the touch screen 112may be analogous to the multi-touch sensitive tablets described in thefollowing U.S. patents: U.S. Pat. No. 6,323,846 (Westerman et al.), U.S.Pat. No. 6,570,557 (Westerman et al.), and/or U.S. Pat. No. 6,677,932(Westerman), and/or U.S. Patent Publication 20020014024A1, which arehereby incorporated by reference herein in their entirety. However, atouch screen 112 displays visual output from the portable device 100,whereas touch sensitive tablets do not provide visual output.

A touch-sensitive display in some embodiments of the touch screen 112may be as described in the following applications: (1) U.S. patentapplication Ser. No. 11/381,313, “Multipoint Touch Surface Controller,”filed May 2, 2006; (2) U.S. patent application Ser. No. 10/840,862,“Multipoint Touchscreen,” filed May 6, 2004; (3) U.S. patent applicationSer.

No. 11/228,758, “Virtual Input Device,Placement On A Touch Screen User Interface,” filed Sep. 16, 2005; (7)U.S. patent application Ser. No. 11/228,700, “Operation Of A ComputerWith A Much Screen Interface,” filed Sep. 16, 2005; (8) U.S. patentapplication Ser. No. 11/228,737, “Activating Virtual Keys Of ATouch-Screen Virtual Keyboard,” filed Sep. 16, 2005; and (9) U.S. patentapplication Ser. No. 11/367,749, “Multi-Functional Hand-Held Device,”filed Mar. 3, 2006. All of these applications are incorporated byreference'herein in their entirety.

The touch screen 112 may have a resolution in excess of 100 dpi. In anexemplary embodiment, the touch screen has a resolution of approximately160 dpi. The user may make contact with the touch screen 112 using anysuitable object or appendage, such as a stylus, a finger, and so forth.In some embodiments, the user interface is designed to work primarilywith finger-based contacts and gestures, which are much less precisethan stylus-based input due to the larger area of contact of a finger onthe touch screen. In some embodiments, the device translates the roughfinger-based input into a precise pointer/cursor position or command forperforming the actions desired by the user.

In some embodiments, in addition to the touch screen, the device 100 mayinclude a touchpad (not shown) for activating or deactivating particularfunctions. In some embodiments, the touchpad is a touch-sensitive areaof the device that, unlike the touch screen, does not display visualoutput. The touchpad may be a touch-sensitive surface that is separatefrom the touch screen 112 or an extension of the touch-sensitive surfaceformed by the touch screen.

In some embodiments, the device 100 may include a physical or virtualclick wheel as an input control device 116. A user may navigate amongand interact with one or more graphical objects (henceforth referred toas icons) displayed in the touch screen 112 by rotating the click wheelor by moving a point of contact with the click wheel (e.g., where theamount of movement of the point of contact is measured by its angulardisplacement with respect to a center point of the click wheel). Theclick wheel may also be used to select one or more of the displayedicons. For example, the user may press down on at least a portion of theclick wheel or an associated button. User commands and navigationcommands provided by the user via the click wheel may be processed by aninput controller 160 as well as one or more of the modules and/or setsof instructions in memory 102. For a virtual click wheel, the clickwheel and click wheel controller may be part of the touch screen 112 andthe display controller 156, respectively. For a virtual click wheel, theclick wheel may be either an opaque or semitransparent object thatappears and disappears on the touch screen display in response to userinteraction with the device. In some embodiments, a virtual click wheelis displayed on the touch screen of a portable multifunction device andoperated by user contact with the touch screen.

The device 100 also includes a power system 162 for powering the variouscomponents. The power system 162 may include a power management system,one or more power sources (e.g., battery, alternating current (AC)), arecharging system, a power failure detection circuit, a power converteror inverter, a power status indicator (e.g., a light-emitting diode(LED)) and any other components associated with the generation,management and distribution of power in portable devices.

The device 100 may also include one or more optical sensors 164. FIGS.1A and 1B show an optical sensor coupled to an optical sensor controller158 in I/O subsystem 106. The optical sensor 164 may includecharge-coupled device (CCD) or complementary metal-oxide semiconductor(CMOS) phototransistors. The optical sensor 164 receives light from theenvironment, projected through one or more lens, and converts the lightto data representing an image. In conjunction with an imaging module 143(also called a camera module), the optical sensor 164 may capture stillimages or video. In some embodiments, an optical sensor is located onthe back of the device 100, opposite the touch screen display 112 on thefront of the device, so that the touch screen display may be used as aviewfinder for either still and/or video image acquisition. In someembodiments, an optical sensor is located on the front of the device sothat the user's image may be obtained for videoconferencing while theuser views the other video conference participants on the touch screendisplay. In some embodiments, the position of the optical sensor 164 canbe changed by the user (e.g., by rotating the lens and the sensor in thedevice housing) so that a single optical sensor 164 may be used alongwith the touch screen display for both video conferencing and stilland/or video image acquisition.

The device 100 may also include one or more proximity sensors 166. FIGS.1A and 1B show a proximity sensor 166 coupled to the peripheralsinterface 118. Alternately, the proximity sensor 166 may be coupled toan input controller 160 in the I/O subsystem 106. The proximity sensor166 may perform as described in U.S. patent application Ser. No.11/241,839, “Proximity Detector In Handheld Device,” filed Sep. 30,2005; Ser. No. 11/240,788, “Proximity Detector In Handheld Device,”filed Sep. 30, 2005; Ser.
